Air filtration materials such as meltblown fabric and electrostatic cotton are electrically charged by means of water electret and electric electret in order to obtain high efficiency. Materials such as glass fibre and PTFE, and filters made of them, can also become electrically charged for various reasons. These electrostatic charges are not completely reliable and will decay over time and with the environment changes, thus affecting the filtration efficiency of the masks and filters. Therefore, the effect of static electricity on the filtration efficiency of filter materials, masks and filters needs to be examined.

This paper interprets the relevant standards, hoping to help understand the relevant domestic and international regulations.

In order to facilitate you to get the performance test method of vacuum cleaner and cleaning robots (automatic/robotic floor cleaning machines, autonomous robotic vacuum), we summarize the standard number for your reference. IEC/EN 60335-2-69, IEC/EN 60312, ASTM F1977-04, IEC/ASTM 62885-7-2020, IEC 63327:2021

The product model SC-FT-1406D and SC-FT-1802D are the best sales Automatic Filter Tester before 2021, nearly 600 customers around the world have the tester. It is used for efficiency (PFE) and resistance test of filter media, mask (respirator) and filter (filter elements).
Scince Purge brand automatic filter tester has been upgraded since December 2021. The model SC-FT-1406D is upgraded to SC-FT-1406D-Plus, and the model SC-FT-1802D is upgraded to SC-FT-1802D-Plus. In fact, we make product improvements all the way according to customers’ feedbacks.
Recently, some new customers who have seen or used model D series come to inquire about the difference between the old and new models.
This article will list the differences in configuration and the improvements made by the new model.

The reliability of "Scince Purge" testing equipment has been recognized by many customers, especially 1406D, 1406YO, 1802D, 1802YO and other models are favored in the second-hand market. Recently, we have received feedback from the market that due to poor use and maintenance, improper operation of untrained personnel,etc, the following problems have occurred. Including the internal parameters of the equipment are confused, the circuit board is corroded, tetc. In addition, we found that some employees who left our company continued to engage in the after-sales service without our authorization, and resell second-hand "Scince Purge" equipment. The above situation will not exclude the behavior of modifying some internal parameters of the equipment in violation of the principles of our company, which will inevitably lead to the distortion of the test results. Therefore, our company decide to take measures helps the end users to identify and avoid the adverse mpact of such events on users.

A multi-functions filtration tester, filter media, medical face mask, N95 mask,FFP mask, filter element of vacuum cleaner, floor sweeper, all of these can be tested.

From March 8 to 10, Scince Purge technology participated in FILTECH 2022 in Cologne, Germany.As a professional exhibition in the filtration industry, FILTECH attracts a large number of professional exhibitors and visitors every time. Affected by the COVID-19 and the war between Russia and Ukraine, t

FILTECH 2022 features 450+ Exhibitors and a major international Conference. Our booth is at Hall 8 Stand D27.
Our products are mainly used to test the filter efficiency and resistance of filter media, mask and filter element of EPA, HEPA filters etc. And the breathing resistance (inhalation resistance and exhalation resistance), leakage air flow (air tightness) of exhalation valve of mask, etc.

Bid farewell to 2021!COVID-19 has been in full two years.Our work and life are not so convenient,The economic situation has also changed,In short, all kinds of troubles. May everyone make progress in 2022!Start with small things,Pay attention to drinking and eating to keep healthy,Develop interests

ISO 23328-1:2008 Breathing System Filters for Anaesthetic and Respiratory Use- Part 1: Salt-test method to assess filtration performance

This part of ISO 23328 gives a method of test for assessing the filtration performance of breathing system filters (BSF).

In the test, the BSF is challenged with sodium chloride particles of the most penetrating size range, 0.1~0.3μm.
